Here are a few Custom Powers I have thought about for various races/classes I am thinking of.
Breath Weapons (costs 5 powers): once per day, the character may use a breath weapon which causes 1d4 damage per level of experience. The available breath weapons are:
30’ long, 10’ wide cone of fire.
20’ long, 5’ wide lightning bolt.
30’ long, 10’ wide cloud of freezing vapor.
20’ long, 5’ wide line of acid.
10’ by 10’ cloud of poison vapor.
This is a weaker version of a Dragon’s breath.
Energy Resistance (costs 3 powers): choose one type of energy or damage - acid, fire, cold, or electricity. The character is immune to mundane versions of this damage - for example a character with Fire Resistance will be immune to regular fires - and enjoys a +4 bonus to saving throws against magical versions of this energy (such as fireballs in the example above. A character may not be resistant to more than one type of energy.
Flagellation: the character can whip herself (literally! or inflict pain on herself otherwise) into a furious religious zeal. She suffers 1 point of damage per level of experience, but gains a +2 bonus to attack and damage rolls and becomes immune to fear. The character may not retreat from combat while this lasts. Furthermore, the Judge may rule that she will have to attack, to the best of her lethal ability, the nearest enemy of her faith, even if the player thinks this is not a prudent choice. The zealous fury lasts until the combat ends.
Martyrdom: upon reaching 0 hit points, the character may choose to remain in full fighting condition, functioning as if she has above-zero hit points, and applying any further damage as negative hit points. She may continue fighting until she reaches a negative number of hit points equal or exceeding her Constitution score, or stays conscious for a number of rounds equal to her level of experience - the sooner between them. Then she falls, unconscious mortally wounded. The price of her sacrifice is that she suffers a penalty of -1 per level of experience to both Mortal Wounds *and* Tampering with Mortality rolls related to that injury.
Rake (also known as Bone-Breaking Strength or Fists of Iron): similar to Fangs and Claws, minus the fangs; thus the claws get stronger at the same cost level. The character gains a claw/claw attack routine. The character can also opt to do non-lethal damage, but in that case he will only be able to do a single attack, as per brawling. This custom power counts as 2 or more custom powers if selected, depending on the claw damage.
2 powers - 1d3-1/1d3-1 damage
3 powers - 1d4-1/1d4-1 damage
4 powers - 1d6-1/1d6-1 damage
5 powers - 1d8-1/1d8-1 damage.
